Category issues with public folder contacts

Hello,

At our association we utilize MS Exchange 2008 and MS Outlook 2007. We have a folder (in public) we utilize to allocate 1550 outlook contacts. We sort out these contacts for email lists for outgoing. Various cards encompass up to 8 categories. Our concern is these cards are mislaying and expanding categories without any person recognizing they have completed the change; there is no warning message asking if one is certain and would like to save the changes.

We have set and locked down the permissions limited only to 4 users who can change a contact card, but to no avail. The contact cards grouping have no truthfulness. We did not ever have this problem with MS Outlook 2003, when categories were in at the bottom part of the contact card in a text field.

Does anybody discern what we could do to fix this issue, without getting back to Office 2003?
